“Without this state-of-the-art machine, I could never have completed the project,” says Rucker. “The machine's unique design enabled me to do high-precision work sitting on a comfortable beanbag.” When the platinum face structure was complete, Rucker turned to the bust itself. This step consisted in making a negative mold of the RP mold in silicone rubber supplied by WACKER. To this end, he was visited in summer 2010 by Cornelia Pohl, head of the Moldmaking Sales team at DRAWIN, WACKER's specialist subsidiary for selling silicone elastomers. In the trunk of her car, she brought with her roughly 45 liters of ELASTOSIL ® M 4601 A/B. This two-component silicone rubber is a classic, tried-and-true molding compound for making non-shrink molds. When these are handled properly, they can be stored for many years and be used at any time, points out Pohl.
